高三下冊英語知識點(diǎn)整理【篇一】


            虛擬語氣在一些特殊詞中的使用或含蓄條件句

  1.wish后的賓語從句。

  與現(xiàn)在愿望不一致,用主語十過去時,例如:

  I wi。hIwere you.

  與過去愿望不一致,用主語+had+過去分詞,例如:Iwish I had visited the White House whenI was in the States與將來愿望不一致,用主語+would (could)+原形。

  2.It's time句型:當(dāng)lt's tine后用that從句時應(yīng)該為主i吾+should+動詞原形或主語十過去時,例如:It,s time thatyou went to school.或It's time that you should go to schooL

  3- If only引起的感嘆句相當(dāng)于“How I wish+賓語從句”。

  (l)If only he could come.他要能來就好了。

  (2)If only I had known the answer.我要早知道答案就好了。

  4.WOuld rather,as if(though)引導(dǎo)的從句也需使用虛擬語氣,表示過去的情況用過去完成時,表示現(xiàn)在與將來的情況用過去時,例如:

  (l)I'd rather you posted the letter right away.

  (2)She loves the children as if they were hers.

  5.含蓄虛擬條件句含蓄條件句是指句中沒有明顯的虛擬條件句,而是利用其他手段來暗示存在虛擬條件。但是這類隱含式虛擬條件句往往都可以轉(zhuǎn)化為if引導(dǎo)的條件句。常用來表示含蓄虛擬條件的手段有:

  (1)介詞或介詞短語。如but for,but that,without,in case of, under more favorable condition等。

  (2)連詞。如so that, unless, in case, supposing,lest, provided(倘若……),for fear that(唯恐),in orderthat, on condition that, if only(要是……就好了)等。

  注意:lest, for fear that和in case引起的從句中謂語動詞多用should+動詞原形,但也可以不用虛擬語氣,而用動詞的陳述語氣形式。例如:The foreign teacher spokeslowly in case we misunderstood him這位外籍教師說得很慢以免我們誤解。

  (3)通過上下文及內(nèi)在含義,句中往往有but,otherwise, unfortunately等類似轉(zhuǎn)折詞。

  without, but. but for, otherwise引起的短語或句子常暗含著含蓄條件。例如:

 、賅ithout you,1 would never know him

 、贐ut for your oooperation, we wouldn't have done it

  ③But that she was afraid, she would have said no. .

 、躨 would be most glad to help you, butI am busy now.

 、軮 would have come to the party yesterday, but ljwas working.

  ⑥I am busy now, otherwise l would do you the favor!

           用來作主語的句子叫做主語從句。如:

  (1)When he was born is unknown. 他生于何時還不知道。

  (2)What he did last night is being investigated. 他昨天晚上干了些什么正在調(diào)查之中。

  在主語從句中須注意:

  1. 主語從句一般用it作形式主語,放在句首,而將主語從句放到句末。如:

  (1)It is possible that he has stolen the car. 很可能他偷了小車。

  (2)Isn’t it strange that he should not have passed the test? 他測試沒有通過,難道不奇怪嗎?

  2. if引導(dǎo)主語從句時,只能用it作形式主語,放在句首,而將if引導(dǎo)的主語從句放到句末。如:

  It is uncertain if he will leave for Beijing tomorrow. 明天他是否去北京還不敢肯定。

  3. that引導(dǎo)主語從句放在句首時,that不可省,但在句末口語中可省。如:

  That he was ill yesterday is known now. 大家都已知道他昨天生了病。

  4. 連接代詞引導(dǎo)主語從句只能放在句首。如;

  (1)Who has broken the glass is unknown. 誰打破了玻璃現(xiàn)在還不知道。

  (2)What he wants is all here. 他所要的東西都在這里。

  5. 主語從句中主句的謂語動詞一般用第三人稱單數(shù)形式,但what引導(dǎo)主語從句的主句謂語動詞的形式須根據(jù)句子的意思來判斷。如

  (1)How he worked it out is still a secret. 他是如何把它做出來的還是一個秘密

  (2)What they makes in this factory are TV sets. 他們在工廠里所做的東西就是電視機(jī)。
